To all whom it may concern: I

Be it known that I, EDWARD J. MODADE, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements n Coupling Devices, of which the following is a specification.

This invention relates to a device'adapted' particularly for coupling or looking ,to5 gether the oil-font and the body-hoop or a lantern, although it is also applicable, in ts main features, to various other articles in which annular or cylindrical members are to be coupled together. 7

The main object of the invention is to produce a coupling-device, of simple and inexpensive form, which will permit the parts connected thereby to be readily engaged with, and disengaged from each other, but which will lock them securely in such engagement.

As applied specifically to lanterns, the invention has the further object of providing for the admission, to the body-hoop, of the wick-raiser of the burner, while closing, against the entrance of air, the slot through which the shaft is introduced.

To the foregoing ends I employ a construction in which the oil-font is locked to the body-hoop by means of a resilient ring, and in which this ring is held securely in operative position by the cam-like action of a rotatable annular member surrounding the body-hoop. I furtheremploy the rotatable member as means for both closing the slot through which thewick-raiser shaft is introduced into the body-hoop, and contributing to the locking action of the device by its engagement with this shaft.

In the accompanying drawings :Figure 1 is a side-elevation, partly in vertical section, of the lower part of a lantern embodying the present invention; and Figs. 2 and 3 are horizontal sections, on the line 3'-3 in Fig. 1, looking upwardly, showing the parts respectively'in unlocked and locked position.

The invention is illustrated as embodied in a lantern of a well-known type, in which the body of the lantern is provided with a downwardly-projecting, cylindrical, sheetmetal hoop 5, while the oil-font 6 is pro vided with an upwardly-projecting cylindrical portion adapted to be received withare coupled together through the" interposition of a divided ring 7 formed .ofresilient wire. This ring has outwardly-bent portions forming. projections 8, which extend as shown inFigs. 2 and,3,the,ring being thus retained within the hoop. ,To cooperate with this ring the oil-font is provided with an annular channel 9. Thenormal form of the ring, as shown in Fig. 2, is

' the hoop. The hoop and oil font l To this end the I body-hoop is surrounded by a rotatable.

annular sheet-metal member 11. This member is provided with openings 12 which, in one position" of the rotatable member, coincide with the projections 8 on the lockingring so that the ringiis free toexpand when the oil-font is. introduced or removed. After i the oil-font has been introduced, however, the rotatable member is turned from its normal position, and this causes it to have V a cam like action upon the projections 8,

forcing them inwardly from the position of Fig. 2 to the position of Fig. 3, and thereby locking the ring against the expansion necessary to permit the removal of the oil-font.

curely in positionby its frictional engagement with the projections 8. i

The oil-font is shown as provided with the usual burner 16, having a wick-raiser of the ratchet type provided with the usual hand-wheel mounted on a shaft 13. A slot 15 in the body-hoop provides for the introduction of this shaft, and the rotatable member 11 is provided with a slot 14 having a vertical portion for the same purpose, this portion of the slot 14 coinciding with the slot 15 when the parts are in the unlocked position of Fig. 2, The upper part. of the slot 14 extends horizontally, and when the member 11 is turned to locking In this position of the parts the rotatable member is, in turn, retained seposition this horizontal portion is engaged with the shaft 13, while the vertical por- 60 through perforations in the body-hoop 5,

tion is moved out of registry with the slot 15. By this arrangement the slot 15 is closed against the admission of air, and at the same time the oil-font is more securely locked in place by the cooperation of the be locked, provided with spaced openings, and a spring-ring interposed between said members and provided with projections eX- tending outwardly through said openings, of a rotatable annular member mounted on said outer annular member, said rotatable member having port-ions cooperating, in the manner of a cam, with said projections on the spring-ring, whereby the ring, through partial rotation of the rotatable member, may be forced inwardly and held inlocking engagement with said inner member.
